So I downloaded and installed the "Mind Warp" optical illusion app, and while it said ''Installing" I went to open up some other app, "photos" i think, and it froze, I held down the switch to turn the iPhone off. Then it was stuck at the reload screen w/ the apple, FOREVER!! There's no way an App from the App Store could do this to my iPhone, right? I figured out how to restore my iPhone even though it was unusable. (hold down both buttons for 30 seconds, then hold down home key and plug into computer and keep holding down home key for another 20ish seconds until this icon pops up on the iPhone) Of course my backup was 'invalid' or 'corrupted' so i had to restore my iPhone as a new iPhone. What a pain in the ass!!!! Doesn't apple screen for viruses like this?
